Description

LDD-250 is a laser diode driver series of medium-power. It was designed to provide current by pulses or in continuous form to laser diodes, laser diode bars and stacks.

Several variants of LDD-250 are offered with different maximum output power (Pmax could be 150, 250 or 400 W), maximum output current (Imax range is 5 ... 100 A), maximum output voltage (Vmax≤ Pmax/ Imax), selected at the moment of order. For more detailed information see user manual.

Devices are encased and easy for the user to mount, they run on common 100‑240 V AC or 200‑240 V AC 50/60 Hz, so you don\'t need any extra power supply for the driver.

Diode drivers were designed to comply with IEC 60601-1 (safety) and IEC 60601-1-2 (EMC). Therefore, modules may be used in different kinds of medical devices without any additional filtration and safety measures, at the same time for the proven compliance to standards for a certain modification the certification procedure is need to be passed, which is available on demand.

We offer also a certified pulsed laser diode drivers for hair-removal application.

Frequently Asked Questions

What is the LDD-series laser diode driver used for?
The LDD-series laser diode driver is intended for driving single laser diodes or laser diode arrays, either by pulses or in continuous mode. It can also be used in medical applications.
What precautions should be taken before operating the LDD-series laser diode driver?
Before operating the LDD-series laser diode driver, you should read the user manual carefully as the equipment may be dangerous. Additionally, ensure that the module is grounded using the M5 stud before connecting it to the mains.
Is external cooling required for the LDD-series laser diode driver?
No, external cooling is not required for the LDD-series laser diode driver as it contains a fan (or fans) for active cooling.
How do you enable the LDD-series laser diode driver?
To enable the LDD-series laser diode driver, apply +5V TTL to the 'Enable' pin on the 15 Pin 'D'-Sub Female interface. The module is disabled if 0V is applied or the pin is unconnected.
What should be done if a fault occurs in the LDD-series laser diode driver?
If a fault occurs, the module will automatically stop operations and set a Fault status. To resolve this, eliminate the fault cause, then disable the module and enable it again.
What type of load should be connected to the LDD-series laser diode driver output?
The output should be measured with an adequate load such as diodes. Connecting a resistive load won't destroy the driver but will severely distort its behavior.
How can the output voltage be monitored on the LDD-series laser diode driver?
The output voltage can be monitored using the 'V OUT monitor' pin on the 15 Pin 'D'-Sub Female interface. The voltage at this pin is proportional to the measured value of voltage on the load.
